If the access control indication information is judged to be access control permission, indicating that the access control process for at least one service is allowed to be started, and continuing to execute the step 202; if the access control indication information is determined to be access control prohibited, it indicates that the access control process for the service is prohibited from being started, and step 213 is executed.

In the embodiment of the present invention, the service to be controlled by access may include a multimedia voice access service or a multimedia video access service.
In the embodiment of the invention, the current service is one of at least one service to be accessed and controlled. For example: the current service may include a multimedia voice access service or a multimedia video access service.
In the embodiment of the invention, when the access control of the current service is triggered in the last period of the cell, the base station stores an access control record, and the access control record is used for recording the information of the access control of the current service triggered in the last period of the cell.
In this step, if it is determined that the access control record of the current service of the cell is stored, which indicates that the access control of the current service is triggered in the last cycle of the cell and is not exited, the step 204 is continuously executed.
In this step, if it is determined that the access control record of the current service of the cell is not stored, which indicates that the access control of the current service is not triggered in the previous cycle of the cell, the step 209 is continuously executed.
In the embodiment of the present invention, the determining whether the current period of the cell is in the congestion state specifically includes: judging whether the ratio of the flow control time of the cell to the statistical time is greater than a first set threshold, and if the ratio of the flow control time of the cell to the statistical time is greater than the first set threshold, indicating that the current period of the cell is in a congestion state; if the ratio of the flow control time of the cell to the statistical time is judged to be less than or equal to the first set threshold, the current period of the cell is not in the congestion state, namely the current period of the cell is in the congestion release state. And the flow control time is the time in the flow control state in the statistical time.
Or, in the embodiment of the present invention, the determining whether the current period of the cell is in the congestion state specifically includes: judging whether the load of a Central Processing Unit (CPU) of a main control board or a baseband board where the cell is located is larger than a second set threshold, and if the load of the CPU of the main control board or the baseband board where the cell is located is judged to be larger than the second set threshold, indicating that the current period of the cell is in a congestion state; and if the main control board or the baseband board where the cell is located is judged to be less than or equal to the second set threshold, the current period of the cell is not in the congestion state, namely the current period of the cell is in the congestion release state.
In this step, when an Operation and Maintenance Center (OMC) easily counts the CPU load value of the main control board or the baseband board where the cell is located, the congestion state of the cell is preferentially determined by using the magnitude relationship between the CPU load value and the second set threshold. Otherwise, adopting the flow control state-time ratio to judge the congestion state of the cell.
In the embodiment of the present invention, the determining whether the current period of the cell is in the disaster state specifically includes: judging whether at least one indication in an Earthquake Tsunami Warning System (ETWS) important Notification (PN) and a commercial mobile phone Warning System (CMAS) message is in a disaster state, if so, indicating that the current period of the cell is in the disaster state; if not, the current period of the cell is not in the disaster state, namely the current period of the cell is in the disaster end state.
If the ETWS PN is judged to indicate a disaster state, the current period of the cell is indicated to be in the disaster state; if the CMAS message is judged to indicate the disaster state, indicating that the current period of the cell is in the disaster state; and when the ETWS PN indication is in a disaster state and the CMAS message indication is in the disaster state, indicating that the current period of the cell is in the disaster state. If the ETWS PN indication is not in the disaster state and the CMAS message is not in the disaster state, the current period of the cell is not in the disaster state, namely the current period of the cell is in the disaster end state.
In this step, if it is determined that the current period of the cell is in the congestion state and the disaster state at the same time, step 205 is continuously performed; if the current period of the cell is determined to be in the congestion relief state, continue to execute step 206; if the current cell period is determined to be in the disaster end state, continue to execute step 206; if the current period of the cell is in the congestion relief state and in the disaster end state, the step 206 is continuously executed.
In this step, when it is determined that the current period of the cell is in a congestion state and a disaster state at the same time, which indicates that the current period of the cell does not satisfy the access control exit condition, the blocking factor corresponding to the current service of the cell needs to be gradually reduced.
In this step, adjusting the step length according to the access class probability factor corresponding to the current service to reduce the blocking factor corresponding to the current service may specifically include: and subtracting the access class probability factor corresponding to the current service from the blocking factor corresponding to the current service to adjust the step length.
In this step, the broadcasting the access control parameter to the ue in the cell may specifically include: and broadcasting a system message (SIB2) to the user equipment of the cell, wherein the system message comprises an access class control parameter to broadcast the blocking factor corresponding to the current service to the user equipment of the cell.
In this step, the blocking factor corresponding to the current service of the cell is reduced, which can improve the proportion of blocking users, i.e. reduce the proportion of users accessing the cell.
In the embodiment of the present invention, if it is determined in step 204 that the current period of the cell is in the congestion relief state, 1 is added to the number of periods during which the cell is in the congestion relief state; if the current period of the cell is determined to be in the disaster end state in step 204, performing 1 addition on the number of periods of the cell in the disaster end state; if it is determined in step 204 that the current period of the cell is in the congestion relief state and in the disaster end state, the number of periods of the cell in the congestion relief state is incremented by 1, and the number of periods of the cell in the disaster end state is incremented by 1.
In this step, if it is determined that the number of cycles that the cell is in the congestion relief state for which the duration is greater than or equal to the length of the backoff of the access class probability factor corresponding to the current service, step 214 is executed; if the number of cycles that the cell is in the disaster end state is determined to be greater than or equal to the length of the fallback step of the access class probability factor corresponding to the current service, execute step 214; if the number of cycles that the cell is in the congestion relief state and the number of cycles that the cell is in the disaster end state are both greater than or equal to the access class probability factor corresponding to the current service when the step is returned, execute step 214; if the number of cycles that the cell is in the congestion relief state for a long time and the number of cycles that the cell is in the disaster end state for a long time are both smaller than the access class probability factor backoff step corresponding to the current service, execute step 208.
In this step, increasing the blocking factor corresponding to the current service according to the access class probability factor backoff step size of the current service may specifically include: and adding the blocking factor corresponding to the current service and the access class probability factor corresponding to the current service to adjust the step length.
In this step, the blocking factor corresponding to the current service of the cell is increased, and the proportion of users who block the cell can be reduced, that is, the proportion of users accessing the cell is increased.
In this step, the broadcasting the access control parameter to the ue in the cell may specifically include: and broadcasting a system message (SIB2) to the user equipment of the cell, wherein the system message comprises an access class control parameter to broadcast the blocking factor corresponding to the current service to the user equipment of the cell.
In the embodiment of the present invention, the initial value is 95%. And when the cell congestion is relieved and then enters the congestion state again or the cell disaster state is ended and then enters the disaster state again, the congestion factor is adjusted from 95 percent to ensure the smoothness of access control. The embodiment of the invention can dynamically adjust the blocking factor according to whether at least one of the continuous periodicity of the cell in the congestion relief state and the continuous periodicity of the cell in the disaster end state is greater than or equal to the access class probability factor backspacing step length corresponding to the current service.
In this step, the broadcasting the access control parameter to the ue in the cell may specifically include: a system message (SIB2) is broadcast to user equipment of the cell, the system message including the access class control parameters. Wherein, the access control parameter does not contain the blocking factor of the current service, which indicates that the access control aiming at the current service is not triggered.
In this step, the broadcasting the access control parameter to the ue in the cell may specifically include: a system message (SIB2) is broadcast to user equipment of the cell, the system message including the access class control parameters. Wherein, the access control parameter does not contain the blocking factor of the current service, which indicates to cancel the access control aiming at the current service.
